Question

State any two functions of Ca2+ in plants?

Answer 1

Answer:

hey answer is here mate

Explanation:

Calcium is considered a secondary plant nutrient. Only nitrogen and potassium are required in larger amounts by plants.

The Functions of Calcium

Every plant needs calcium to grow.

Once fixed, calcium is not mobile in the plant. It is an important constituent of cell walls and can only be supplied in the xylem sap. Thus, if the plant runs out of a supply of calcium, it cannot remobilize calcium from older tissues.

If transpiration is reduced for any reason, the calcium supply to growing tissues will rapidly become inadequate

Answer 2

Two functions of $Ca^{2+}$ in plants

Explanation:

• As $Ca^{2+}$ is required in relatively large quantities by plants, it is called as a macro nutrient.
• It is required by the meristematic and differentiating tissues and also gets accumulated in the older leaves and is seen in the cell wall.
• It is required by the plant to form a mitotic spindle in cell division and also is required for the development of the cell wall.
• It plays a vital role in regulating metabolic activities and is also involved in activation of enzymes required for the growth of root and shoot tip.
